How the Mini Hydraulic Hand Operated JIB Crane works
- The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine.
- The Hydraulic jack / cylinder gives large force from a small input using fluid pressure.
- Motion is transmitted through linkages, cam and lever parts, which set the speed, torque and direction at the working end.

Mechanical viva questions on this project
What is the aim of the Mini Hydraulic Hand Operated JIB Crane project?
A hand-operated hydraulic jib crane for workshops and warehouses. A hydraulic cylinder raises the jib arm to lift loads, and the arm swings to place them where needed.
Explain the working of your project in short.
The mild steel frame and fabrication forms the base that carries every other part, so it is designed first from the load and size of the machine. The Hydraulic jack / cylinder gives large force from a small input using fluid pressure. Motion is transmitted through linkages, cam and lever parts, which set the speed, torque and direction at the working end.
What is Pascal's law?
Pressure applied to a confined fluid is transmitted equally in all directions. A small force on a small piston creates a large force on a larger piston.
What does a cam-follower mechanism do?
It converts rotary motion of the cam into reciprocating motion of the follower, with the displacement profile set by the cam shape.
Why is mild steel used for the frame?
It is cheap, strong, easy to cut and weld and widely available. A frame of 25 mm square pipe is enough for most student models.
Which material did you select for the main parts and why?
Mild steel (MS) is used for the frame because it is strong, cheap, easy to cut and weld and available everywhere. Shafts are made of EN8 or bright mild steel for strength, and parts that do not carry load can be aluminium or acrylic to reduce weight.
What factor of safety did you take in your design?
A factor of safety of 2 to 3 is taken for static parts and 3 to 5 for parts under shock or fatigue loading. Allowable stress = yield strength ÷ factor of safety, and each part is checked against it.
How did you estimate the cost of the project?
The cost is the sum of raw material, bought-out parts, machining or fabrication and overheads. Our estimate for this model is about ₹8,200 to ₹12,000, depending on size, material and the workshop rates in your city.
Which manufacturing processes were used?
Cutting and grinding of sections, arc or MIG welding of the frame, drilling for mounting holes, followed by assembly, alignment and painting.
